[PATCH v2 1/2] ASoC/soundwire: remove is_sdca boolean property

From: Bard Liao
Date: Thu Nov 17 2022 - 21:56:28 EST


From: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx>

The Device_ID registers already tell us if a device supports the SDCA
specification or not, in hindsight we never needed a property when the
information is reported by both hardware and ACPI.
